consists of inwardly extending members. such as the annular anges G,which are secured to the inner surfaces of the side walls Q, vbeingpreferably formed integral therewith and are strengthened by stitching-through said body portion, as shown at 6, These flanges extend inwardlyto points near the center of the tire and are there connected one to theother, preferably by means of an ordinary lacing thong? which permitsthe flanges to be connected one to the other after the tire has beenotherwise completed and forms 'a strong, firm connection between the twomembers.

- A. suitable inwardly extending projection, such as the radial rib 8,is carried by the inner surface of the`oi1tei` Wall 4- and is preferablyformed integral *with that outer wall. yThis rib extends inwardly to vapoint sli htly beyond the pointsl of connection o the flanges 6 to theside walls 2 and engages the out'ersides of those flanges near theirpoints of connection one to` the other, the inner edge of the rib 8being, in the present instance, beveled on its oppositeI sides to permitthe saine to lit snugly against the adjacent edges of the flanges.Inasinuch as the rib 8 engages the flanges 6 at a point beyond theirpoints of connection to they side walls 2, it will be apparent thatthese flanges will extend at an acute fangle to said rib and that theywill serve not only ito prevent the spreading of the side tvalls, butthe strain imposed thereon by the rib 8 will come upon B e'it known thatI, VICTOR E. RUMBARGER, a citizen of the United States, residing at,State of Ohio, .have'invented certain new Dayton, in the county yof`Montgomery and and useful Improvements in Cushion-lires` Aof which thefollowing is a` specification, reference being had therein to theaccompanying drawings.

This invention relates to cushion tires for 'necessary resiliency toenable it to absorb the shock incident to the irregularities of the roadwhich will not be li'ableto collapseas a.result of either a heavy loador long use, thereby piovidinP at-ire which will have all the advantagesoiF a pneumatic tire withoutbeing susceptible to the injuries cominon tothat tire and further, to provide adequate means for readily attachingsuch a tire to and detaching the same from the rim of the vehiclewheeel.

With these objects in viewmy invention consists in certain novelfeatures of construction and in certain parts and combinationshereinafter to be described, and then more particularly pointed out inthe claims.

ln the accompanying drawings, Figure-l is ay transverse sectional viewof the rim of -a wheel and a tire embodying my invention;

cient and of sucha character as to cause the tire to instantl;v resume.its norinal position when the irregularity in the road has been passed,thereby forming what known as a' "lire" tire. rThus. it Will be seenthat lY l have provided a tire Which is practically a hollow tirehavingall the resiliency and adn \f'antages`ot a pneun'iatic tirewithout being dependent upon compressed air to maintain i the saine inits extended condition, this being accomplished byv the connectingflanges t3 and the radial. rib S Which prevent the tire troincollapsing, but, at the saine tiine, allo the saine sutlici'entresiliency to absorb the g shock incident to the passage of the tireover an uneven road. It will also be ap parent that a tire of thisconstruction tot only nnsusceptible to puncture and injuries of a likecharacter, but that the/.saine will be niuch n'iore dura ble and 'willhave a -inuch longer terni of service.

In order that this tiro may be readily at-' taehed to and detached fromthe Wheel l have pr ,\\'ide d the telly S) otl the wheel with a platel() which is scoured to the outer sur l l l l l face thereot' and hasone side turned upon to torni a recess adaptj ed to receive one ot theprojections: Pl carried ll b v the side wall 'l`lie opp .isite sii/lcot' the l plate vlt turned inwardly along the Sitte of j the telljvr iland then laterally. as shown at l2, to forni a support for-'one edge ofan annular plate orring- 13, which is detachably j securedto the riin 9by ineans ot screws la i and has its outeredge turned inwardly, asshorvn at; l5, to engage the projection 3 of l the other side -wall ofthe tire and secure this projection in the recess formed between theinturned edge l5 and the plate 10. In order to retain the projectionsWithin their respective recesses. l insert a suitable. spacl ing`nieniber l. et\veen the adjacent surface of l the side Walls near theinner edges thereot', j and, in the present instance, l hate shown thisspacingnieinber as comprising! a rim or l band 1.6 ot' nietal haring;`its edges bent inl Wardly to conform to the shape of the side l Walls 2of the tire. This ring tits about the plate l0, Which fornis the outersurface of i the telly Q and is preiterabij.v looselyinonntcd l thereonso that the same can be inoved to one I side to permit. the projection 3carried by ,J
